@kluyvert I'm adding to the SCS Toolbox documentation a simplified and reduced version of your notebook concerning the azimuthal integration of DSSC with pyFAI. Please let me know if that's ok with you or if I should change something (acknowledgment, links, whatever). Thanks.

That's absolutely fine. As I mentioned, I'm planning to wrap the code to make a PyFAI detector object (and maybe an azimuthal integrator as well) up as a method in EXtra-geom - once that's available, I'd encourage you to update the example notebook to use it, which will save a few lines. We've got an issue about that here: https://github.com/European-XFEL/EXtra-geom/issues/135

BTW, where the example has Detector(236e-6, 204e-6), Jérôme pointed out that the dimensions are the wrong way round: it should be Detector(204e-6, 236e-6). It doesn't seem to make any difference for this, because we give coordinates for every corner of every pixel anyway, but we may as well have them correct.

Fixed the Detector arguments, thanks.
